Arthur is 90 years old. He's played golf every day since his retirement 25 years ago. One day he arrives home looking downcast. "That's it," he tells his wife. "I'm giving up golf. My eyesight has become so bad that once I hit the ball I couldn't see where it went."

His wife sympathises and makes him a cup of tea. As they sit down she says, "Why don't you take my brother with you and give it one more try."
